The wide range of uses of Moringa oleifera in recent time has witnessed increasing demand of its foliar and seed products in nutritional, medical and ecological applications. The upsurge of demand for these products needs to be balanced with new varieties of improved performance to meet the supply chain. To achieve this, morphological diversity assessment is prerequisite for future crop improvement programme. Therefore, numerical analyses of the external morphology of leaf and fruit of thirty accessions of Moringa oleifera were assessed. The study was carried out on both qualitative and quantitative characters to assess the diversity at morphological level to establish the phenetic relationships and the delimitation of accessions. Relationship studies showed considerable correlation between the leaf and fruits characters that produced clear and reproducible threats and were selected for diversity study. Numerical analysis of the qualitative and quantitative characters clustered the accessions into five groups – operational taxonomic units (OTUs) 1, 2, 3, 4, 5, 7, 9, 10, 11, 12, 13, 14, 17, 18, 19, 20, 21, 22, 24, 25, 26, 27, 28, 29, 30 were clustered in group one; OTUs 6 and 8 were clustered in group two and three respectively; OTUs 15 and 16 in group four and OUT 23 in group five cluster membership. Principal Component Analysis was carried out to augment the Cluster Analysis which showed large morphological diversity existing in accessions of Moringa oleifera hence, infraspecific classification is hereby proposed.  These analysis particularly traits related to leaf and fruits yield can also be utilised for crop improvement programme.

Forty-four hyacinth bean genotypes were evaluated for different qualitative and quantitative characters during July 2005 to February 2006 at Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur. The genotypes showed considerable variations for most of the morpho-physical traits. Shape, size and colour of vein, leaf, petiole, stem, flower, pod and seed varied among the genotypes. Days to first flower ranged from 47.6 to 136.3 days indicating the presence of early variety. Individual pod weight varied from 1.47 (HB042) to 12.3g (HB009). The genotype HB027 produced the maximum number of pods/ plant (425) closely followed by HB001 (385). Similar trend was observed for pod yield/plant. The genotype HB027 produced the highest pod yield/plant (3.45kg) followed by HB001 (3.35kg). 100-green seed weight ranged from 4.0g to 73.33g, which indicated the presence of bold seeded genotypes. Among the genotypes, HB027 and HB007 produced very bold green seed and higher green pod yield/plant, therefore, they can be selected for both pod and green seed production purpose.

The subject of this paper is to evaluate criteria in the decision-making process for choosing new usable office facilities in light of a big company or public service seeking for new usable office facilities. The criteria defining the requirements for individual selection variants enter into this decision-making process. These criteria have qualitative and quantitative characters. In order to model the criteria, it is desirable that their values are standardized. The method of standardization of these criteria is given in this paper. In this paper, attention is paid to the decision-making process in the course of choosing new usable facilities in administration objects. This decision-making process is based on input data analyses and on conclusions for a certain selection variant resulting from them.

Seed morphology of 12 Iranian endemic and subendemic species of Veronica was studied using scanning electron microscope (SEM). Seven qualitative and quantitative characters were measured using SEM micrographs and stereomicroscopy. The seed shape of most species is ovate and plano-convex. The size of seeds ranges from 1.25 x 0.75 mm in V. khorassanica to 2.5 x 1.75 mm in V. viscosa Boiss. The ornamentation of seed coat is reticulate-verrucate in V. khorassanica, V. czerniakowskiana, V. mazanderanae and V. rubrifolia, reticulate-rugate in V. acrotheca, V. aucheri, V. viscosa and V. intercedens, rugose in V. microcarpa, V. chionantha and V. rechingeri, and reticulate-porate in V. gaubae. The testa cells are polygonal in ten species and irregular in two species. Micromorphological characters of seeds are useful in specific and subspecific delimitations of Iranian Veronica.

Fifteen strawberry germplasm collected from local and exotic sources were evaluated for different qualitative and quantitative characters. The germplasm showed variation for majority of the studied traits. Plant height during peak harvest ranged from 14.67 to 25.00 cm and FA 007 exhibited the tallest plants. The maximum number of leaves plant-1 was produced by FA 006 (46.67). The maximum number of runners plant-1 was obtained in FA 003 (68.67) followed by FA 004 (63.00), while the highest number of crown plant-1 was found in FA 007 (15.33) followed by FA 006 (14.67). Days to flowering varied from 48.33 to 102.30 among the germplasm and FA 008 required minimum (48.33) days for flowering. The germplasm FA 004 produced the highest number of flower trusses (35.50 plant-1) while it was the lowest in FA 010 (5.00 plant-1). The number of flowers plant-1 was found maximum in FA 003 (168.00 plant-1) and minimum in FA 010 (40.00 plant-1). Among the germplasm pollen viability varied significantly and maximum viable pollen was recorded in FA 010 (84 %), while it was lowest in FA 004 (12.00 %). The highest per cent fruit set was recorded in BARI Strawberry-1 (86 %) while, FA 013 (39 %) showed the lowest. Among the germplasm the highest yield plant-1 was recorded from FA 005 (737.70 g) followed by FA 006 (702.30 g) and was significantly higher than others while the lowest yield plant-1 was recorded from FA 013 (52.00 g), FA 014 (69.00 g), FA 009 (81.33 g) and FA 010 (121.30 g).

A study of genetic divergence in 40 brinjal (Solanum melongena L.) genotypes for various characters to study the diversity based on qualitative and quantitative characters. Significant variations were observed among the brinjal lines for all the parameters under study. Based on D2 values, the accessions were grouped into seven clusters. Average intra- and inter-cluster D2 values among 40 genotypes revealed that cluster II showed a minimum intra-cluster value of 3.793, indicating that the genotypes within this cluster were similar, while the cluster I showed maximum intra-cluster D2 value (4.681) revealing the existence of diverse genotypes in these clusters. The inter-cluster D2 values ranged from 4.657 to 7.174. The minimum inter-cluster D2 value was observed between cluster III and IV (4.657), indicating the close relationship among the genotypes included in these clusters. The maximum inter-cluster value was observed between cluster V and II (7.174), indicating that the genotypes included in these clusters had maximum divergence. Hence, hybridization between the genotypes included in these different clusters may give high heterotic responses and thus better segrigants are greatly suggested for selection and improvement of brinjal crop with good consumer preference and high fruit yield.

A computerbased key for identifying plant parasitic nematodes of temperate agriculture in New Zealand and around the world is described It uses the Lucid software developed at the University of Queensland and includes images of major diagnostic features The key is multiaccess rather than dichotomous so may be entered at any point allowing for the most obvious characters of a specimen to be scored first and thereby immediately reduce the number of likely taxa Both qualitative and quantitative characters are used The key requires that the specimen can be viewed microscopically but examples of most morphological terms are illustrated so the nonspecialist should be able to make use of the key

The pale yellow-seeded Amaranth is virtually a new crop in Nigerian agriculture. Under the sponsorship of the National Agricultural Research Project (NARP), 12 accessions were evaluated for agronomic characters and yield attributes in three agro-ecological zones of the country. The results showed significant variation in the agronomic characters of the accessions. Top accessions recorded average grain yields of 4.5, 3.5, and 2.6 t·ha–1 in Sudan savanna, derived savanna, and guinea savanna zones of the country, respectively. Response of the accessions to qualitative and quantitative characters in the zones are discussed.
